10-Thiosubstituted derivatives of pentahydroxyanthracene with application in the organic optoelectronics, new method of production and intermediate compounds

摘要

The present invention relates to the novel fused aromatic hydrocarbons represented by the general formula 1, wherein R- is alkyl having 1 to 12 carbon atoms, benzyl, phenyl, naphthyl, having application in organic optoelectronics. The present invention also relates to intermediates and a process for the preparation of fused aromatic hydrocarbons of the formula 1, based on the transformation reaction of intermediates, in the presence of FeCl 3 /Kl, in a boiling organic solvent, especially methanol, in a single reaction vessel, without the need of isolation of intermediates.
